On Sunday, Lakeland announced that it was stepping up production of its protective apparel for use in handling the Ebola virus for global availability.

"In response to the increasing demand for specialty protective suits to be worn by healthcare workers and others being exposed to Ebola, Lakeland is increasing its manufacturing capacity for these garments and includes proprietary processes for specialized seam sealing, a far superior technology for protecting against viral hazards than non-sealed products," it said in a statement.

Lakeland also said the US State Department had ordered 160,000 of those suits.

US authorities confirmed Sunday that there was a second case of Ebola in the country.

Texas Health Presbyterian Hospital Dallas announced that one of its staff members had contracted Ebola, marking the first case of infection inside the United States.

Ebola has killed more than 4,000 people in West Africa -- most of them in hardest-hit Guinea, Sierra Leone and Liberia -- since the start of the year. The highly contagious virus is spread through contact with the bodily fluids of infected persons and the epidemic appears to be outpacing efforts to fight it.
